Let's look at the patch, to see what it looks like before editing it:
```
$ rad patch show 89f7afb

```
We can change the title and description of the patch itself by using a
multi-line message (using two `--message` options here):
```
$ rad patch edit 89f7afb --message "Add Metadata" --message "Add README & LICENSE" --no-announce
$ rad patch show 89f7afb

```
We prepare the file `revision-edit.json` which contains one action (thus one line) to be applied.
``` ./revision-edit.jsonl
{"type": "revision.edit", "description": "Add README and LICENSE", "revision": "89f7afb1511b976482b21f6b2f39aef7f4fb88a2"}
```
We now use `rad cob update` to edit the patch another time, rewriting the description.
The action itself is of type `revision.edit` and carries the parameters `revision`,
specifying the revision for which the description should be changed, and `description`,
specifying the new description.
```
$ rad cob update --repo rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --type xyz.radicle.patch --object 89f7afb1511b976482b21f6b2f39aef7f4fb88a2 --message "Edit patch" revision-edit.jsonl

$ rad patch show --verbose 89f7afb

```
Notice that the patch now has the description `Add README and LICENSE`.
We may use `rad cob update` to create a new revision altogether, as well.
Let's create yet another commit, an empty one this time, and do that.
```
$ git commit --allow-empty --message="Dummy commit for a new revision"
[changes f1339dd] Dummy commit for a new revision
```
We prepare the file `revision-create.jsonl` which contains one action.
``` ./revision.jsonl
{"type": "revision", "description": "A new revision", "base": "f2de534b5e81d7c6e2dcaf58c3dd91573c0a0354", "oid": "f1339dd109e538c6b3a7fed3e72403e1b4db08c9"}
```
Attempting to create the new revision right away would fail:
``` (fail)
$ rad cob update --repo rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --type xyz.radicle.patch --object 89f7afb1511b976482b21f6b2f39aef7f4fb88a2 --message "Create new revision" revision.jsonl
✗ Error: store: update error: failed to read 'f1339dd109e538c6b3a7fed3e72403e1b4db08c9' from git odb
```
Since we are not using the remote helper `git-remote-rad` here, we need to push
the new commit to storage manually. See `fn patch_open` in `/radicle-remote-helper/src/push.rs`
for more details.
```
$ git push rad HEAD:tmp/heads/f1339dd109e538c6b3a7fed3e72403e1b4db08c9
$ git push rad :tmp/heads/f1339dd109e538c6b3a7fed3e72403e1b4db08c9
```
Now we can invoke `rad cob update`:
```
$ rad cob update --repo rad:z42hL2jL4XNk6K8oHQaSWfMgCL7ji --type xyz.radicle.patch --object 89f7afb1511b976482b21f6b2f39aef7f4fb88a2 --message "Create new revision" revision.jsonl
